HOUSTON --

Authorities are investigating after a family-of-four was found dead Thursday night in a northwest Harris County home.

Deputies say two young boys their mother and 50-year-old father were all found dead around 7:30pm Thursday at the home in the 14000 block of Fosters Creek.

"They were busy, involved in a lot of stuff and everything, but they were always really nice, and we just talked to them a couple of days ago," a neighbor told us.

Investigators say a family friend made the horrible discovery while checking on the parents who had not been to work. The two boys, according to neighbors, were in the second and fourth grade at Sampson Elementary School, and were active in sports.

On Friday, the children's cub scout group and neighbors gathered to hold a vigil in their honor.

"I just felt like I needed to come out and pay respects," neighbor Jessica Thompson said.

Investigators are saying very little as they investigate the deaths.

"Even my children are curious. They want to know what happened but none of us know what happened," said Roxie Allen with the Boy Scouts of America.

Hours before the vigil, a neighbor told Eyewitness News there has been some domestic conflict but nothing that would lead to this result.

"There had been some arguments but that's about as much as we know," one neighbor said.

The father was an engineer at Cameron. So far, the company has no comment on this tragedy. The parents immigrated from China. Records show the mother was a partner in a sushi restaurant at one time, but what caused this event is still very much a mystery.

"He seemed to be really nice one-on-one. She seemed to be really nice one-on-one. The kids were your normal run of the mill kids, playing out in the front yard, riding their bicycle, just like any typical family," neighbor Randall Duncan said.

Officials say they're waiting for autopsy results to determine the causes of death. Their names have not yet been released.

Meanwhile, grief counselors will be on hand at the boys' elementary school.
